## Capacitor Guide – Summary

Capacitor is an electronic component that stores and controls electrical energy and is an essential element used in printed circuit boards (PCB’s). Choosing a capacitor depends on the circuit and applications. There are some parameters […]

## Capacitor Colour Code Values with Examples

To use a capacitor in your electronic projects, understanding capacitor colour code is required. For identifying the capacitor values and tolerances international colour coding scheme (electronic colour coding) was introduced. Every capacitor has colors or […]

## Resistors in Series Connection

When a number of resistors are connected in such a way that the end of first resistor is connected to beginning of second resistor and the end of second one to third resistor and so […]

## Introduction to Capacitor

The capacitor is the basic electronic component that is used for storing, surge suppression and filtering. It is a widely used and important component in the family of electronics. Like resistor, capacitors are passive components […]

## Alternating Current (AC) vs. Direct Current (DC)

Electric current is the amount of electric charges that passes through a wire with respect to time. When battery is connected across a conductor, electrons move from negative terminal to positive terminal of battery. They […]

## Electricity Basics

Basic Electricity is the presence of motion of electric charges. Electricity is all around us powering houses, offices and technologies like our cell phones, computers, lights, soldering irons, and air conditioners. We can’t imagine this […]

## Drift Current Drift Velocity and Electron Mobility

As you all know that an electric conductor has free electrons inside them, due to movement of these free electrons, current is produced and when we give them energy via connecting battery, the electrons move […]

## Conventional Current vs. Electron Current

Electron current and conventional current are two types of notation we use to mention current flow in a circuit. These two notations are opposite to each other. We need a notation to do some calculations […]

## What is Electric Current?

Electricity is a great gift science that has given to mankind. We use electricity almost all the time and it has been a part of our modern lifestyle. We can’t even imagine our lives without […]

## What is GPS and How does it work?

Introduction Have you ever thought of locating yourself on the blue planet (Earth)? This might be a tough question if you are residing in a new place. But don’t worry, the answer is simple, the […]
